Method for designing nearly circularly symmetric descreening filters that can be efficiently implemented in VLIW (very long instruction word) media processors
A method is disclosed for designing two separable filters, LPP & HPP, that approximates the circularly symmetric frequency response achievable using a non-separable filter. The method selects a cut-off frequency and designs a 1-D low pass filter. Next, the method obtains a low pass 2-D filter an...
